PCA analysis to estimate the discriminatory power of immune markers in children with PIMS-TS, COVID-19, seropositive and controls

PCA (Principle component analysis) plot computing normalized ELISA data from plasma levels of selected cytokines, chemokines and growth factors in combination of four different experimental groups first PIMS-TS (Coloured in brown) vs COVID-19 (Coloured in red) vs seropositive (Coloured in blue) and controls (Coloured in green). The PCA shows the two principal components of variation, accounting for 12.2% (x -axis) and 50.4% (y -axis) (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
